+apps/interpreters README file
+=============================
+
+This apps/ directory is set aside to hold interpreters that may be
+incorporated into NuttX.
+
+pcode
+-----
+
+  At present, only the NuttX Pascal add-on is supported.  This NuttX add-on
+  must be downloaded separately (or is available in an SVN snapshot in the
+  misc/pascal directory).
+
+  This Pascal add-on must be installed into the NuttX apps/ directory.  After
+  unpacking the Pascal add-on package, an installation script and README.txt
+  instructions can be found at pascal/nuttx.
+
+  INSTALL.sh -- The script that performs the operation.  Usage:
+
+     ./INSTALL.sh [-16|-32] <install-dir>
+
+      If you are using this standard NuttX apps/ package, the correct
+      location for the <install-dir> is apps/interpreters.  That is
+      where the examples and build logic will expect to find the pcode
+      sub-directory.
+
+    Example:
+  
+      ./INSTALL.sh -16 $PWD/../../../apps/interpreters
+
+    After installation, the NuttX apps/interpresters directory will contain
+    the following files
+
+      pcode
+      |-- Makefile
+      |-- include
+      |   `-- Common header files
+      |-- libboff
+      |   `-- Pascal object format (POFF) library
+      `--insn

+          |   `-- model-specific header files
+          `-- prun
+              `-- model-specific source files
+
+  pashello
+  
+    There is a simple Pascal example at apps/examples/pashello.  This is the
+    standard "Hello, World!" example written in Pascal and interpreted from
+    Pascal P-Code at runtime.  To use this example, place the following in
+    your appconfig file"
+
+      # Path to example in apps/examples containing the user_start entry point
+
+      CONFIGURED_APPS += examples/pashello
